(a) Effective Date This airworthiness directive (AD) is effective August 18, 2022. (b) Affected ADs None. (c) Applicability This AD applies to Saab AB, Support and Services Model 340A (SAAB/SF340A) and SAAB 340B airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2021-0273, dated December 8, 2021 (EASA AD 2021-0273).
